GMO x Banana Punch #9: Ripe banana flavor with GMO on the exhale. Persy Rosin is made by pressing only the finest spectrum of Water Hash - 90u - from the first wash, refined using only heat and pressure to create a flavorful and easy-to-consume oil. Persy means personal, and like your personal stash, you save the best for that special moment. This is our favorite form of fresh press rosin.
